Thanks for tuning in this afternoon! Stay with Sky Sports for the full match report and all the reaction.
It's all over! United beat Norwich 4-0 thanks to Kagawa's hat-trick and a sweet strike from Rooney late on.
Turner does well on the stretch to prevent Welbeck getting to a ball in the box and that looks like it could be it...
Cleverley gets forward as we near the full-time whistle but the hosts are kept at bay as Norwich carry on in damage-control mode.
Valencia tries to pick someone out with a through-ball into the box but it somehow evades both Rooney and Kagawa and rolls back to Bunn.
United are sitting comfortably on the ball as the minutes trickle down. It's unfortunate for Norwich, who did well in the first half but have been truly worn down since that opening goal.
It's a sweet strike from Rooney, who's been great in a creative role today and has got his moment in the spotlight late on.
What a goal from the striker, who drops his shoulder to lose Johnson before applying a lovely dipping finish from range to defy Bunn. Fantastic finish.
It looks up all wrapped up for United now and Kagawa will feel he's definitely staked his claim for a spot against Real on Tuesday night.
It's the Japanese player that starts the move as he picks out Welbeck in midfield and the striker finds Rooney, who passes back to Kagawa in the box. He takes a couple of good touches before dinking it into the back of the net over Bunn. Quality stuff again from the United man.
De Gea, who hasn't had much to do today, does well to keep a long ball inside and he feeds it back to his defenders.
The spark seems to have gone out of this Norwich side after the second goal and it looks like United just need to steer this home.
Evans deals with a throw in from Garrido and rolls a leisurely ball back to De Gea, with United in no hurry now.
Valencia gets the better of Garrido down the right and drives the ball into the box, with Rooney and Kagawa lurking, but the former gets in the way and can't create something.
After that lull in play the action resumes, with Welbeck gingerly getting to his feet. It looks like United are home and dry but injuries are still a worry for Ferguson ahead of the clash with Real.
Welbeck is left floored after an over-eager challenge from Turner in midfield. It's a clumsy one and he might be looking at a yellow.
We're into the final 10 minutes and United are closing on extending their lead at the top to 15 points. Norwich will have to quickly regroup if they're going to strike back.
"The city is ours" is the chant ringing out through Old Trafford. United are looking for another as Kagawa and Carrick swap passes.
Nice movement from United there for that goal and they'll be feeling pretty comfortable now, with the mood in the stadium much more jubilant.
Rooney does brilliantly to lose Bassong as he pounces on a long, impeccable ball into the box from Carrick then unselfishly dishes it out to the onrushing Kagawa, who rolls it home.
There's been confirmation Johnson was in fact booked for that challenge on Rooney a few moments ago - not too surprising.
Cleverley's second touch is lacking as he tries to slot through for Kagawa in the penalty area but his effort is a wayward one.

Another change for Norwich as Snodgrass goes off after putting a real shift in, with Bennett coming on in his place.
Rooney's caught in midfield by Johnson after a sudden change of pace and he lifts his hand immediately in apology. He's perhaps lucky not to get a yellow.
Here he comes then, Kei Kamara replaces Wes Hoolahan. Can he repeat last weekend's heroics? Worth noting he's already scored against United in a pre-season friendly back in 2010.
Anderson and Rooney attempt a one-two but some good screening from Howson foils them on the edge of the box.
Carrick is chased down by Howson as he tries to force an error from the United man in the hosts' half but he manages to roll back to De Gea.
Rooney's long ball forward seeks out Evra on the left but the Frenchman is flagged offside and the ball goes back to Bunn, who's battling on.
Valencia tries a run down the right and Garrido earns himself a booking to add insult to injury after he's nutmegged by the winger.
Norwich have a free-kick in midfield which Martin lofts in but Vidic beats Holt to the ball as they both rise to meet it.
Welbeck is straight into the mix as he tries to set up Valencia on the edge of the box but he can't get a shot away under pressure from the Norwich defence.
Van Persie's afternoon is over, anyhow, as he makes way for Welbeck. He seems ok after that earlier injury scare though.
Rooney tries his luck with a shot across goal from the edge of the box but can't catch it right, and Van Persie appears peeved he didn't pass.
Howson slips through Snodgrass but he's squeezed out at the back for a United goal-kick. It appears Van Persie could come off for United.
Bunn looks hurt again after a slight knock with Van Persie as he comes out to collect but he's carrying on.
There's a big chance for Norwich but the ref blows his whistle for an apparent foul on Evra from Holt as he heads the ball on to Martin, but his shot is skewed over the bar from two yards anyway.
Norwich are making United work here. There's another spell of tidy passing play as Hoolahan and Garrido link up in midfield.

Hoolahan tries his luck with a powerful shot from range which takes a nick off Carrick and hands Norwich another corner.

There's a spell of neat build-up in midfield from Norwich but Holt's ball, attempting to free Snodgrass, goes wayward.
Valencia attempts a cross into the box from the right and he's denied by Martin as United win a corner.
The delivery is guided towards Bassong, who jumps to greet it, but Evra is there with him and he can't get enough on it to head towards goal.
Another long Carrick ball up towards the box is dealt with by Turner and rolled back to Bunn in goal. Vidic outmuscles Holt as they both go for the goal-kick and Norwich have a free-kick.
United exchange passes, looking for a way through, and Carrick's long pass is seeking Robin van Persie but he's flagged offside.
Rooney makes a good run to lose Turner but some more solid goalkeeping from Bunn foils him again as the keeper comes out to clear.
Norwich have started well this half and United will be glad to get some possession as they trade passes at the back.
It's Vidic again that deals with the delivery before a well-timed tackle from Smalling halts Snodgrass, on the charge again.
There's a chance for Norwich as a great ball in from Russell Martin very nearly finds Snodgrass but Vidic just manages to put it behind. Canaries corner.
United take a quick free-kick in the middle of the park after a foul on Evra but Norwich snatch back possession, trading passes out on the right.
Howson's attempted pass to Johnson is intercepted by goalscorer Kagawa to halt a spell of Norwich attack. He atones when he intervenes on a United pass seconds later.
Pilkington tries his luck with a long ball forward but it goes straight back to De Gea again. Vidic gets the ball away from Hoolahan on the edge of the box as Norwich come out brightly this half.
There's apologies from Holt as his delivery flies straight through to De Gea without troubling anyone.
It's Norwich that kick us off this half as they look for a way back from that 1-0 deficit. Smalling concedes a free-kick in the Norwich half.
It's almost time to get back underway. Thanks for all your comments at the break and enjoy the second half!
Flattery gets you everywhere Peter Reid - "Nice to see Kagawa on the score-sheet today. Had 2 - 0 on my 'Super 6' and I now hope that RVP stays on the pitch to double the score. Commentary simply awesome - at least one entry for every single minute and sometimes two entries per minute. It's like watching the game."
@Pedzyy tweeted - "We are not playing like we usually do, poor passes and all sorts but I have a feeling it will end 3-1 or 2-0 to Utd!"
Zac Wiles says - "I think United need to be more clinical and finish the game off as early as possible with Real Madrid in mind. Plus take RVP off as a precaution and bring Welbeck on. I reckon 3-1 United."
@martinT1902 feels Kei Kamara is the answer for Norwich in the second half - "well we nearly held out. Proud of our defending and what ever you get at Old Trafford is a bonus. Bring on Kamara! OTBC"
@paulbienkowski has tweeted - "Good first half but Norwich were parking the bus. Great goal from Kagawa. United need to score a second & frustrate Norwich."
Gary's email came just before the breakthrough and now he's added - "Good to see Kagawa was listening to what I said!!"
Gary Hunter has been in touch to say - "Too many poor passes by United, Kagawa and Rooney need to wake up as well."

Norwich were holding their own up until that stoppage-time strike and it will be interesting to see if the momentum swings in the second half.
The whistle blows and that half ends United 1 Norwich 0. The Red Devils will be reasonably happy with the scoreline but have some concern ahead of the Real Madrid clash on Tuesday, with Van Persie appearing to hurt himself in the build-up to the goal and Evra floored by Snodgrass seconds before the break.
Ferguson is not happy after that challenge on Evra, with United down to 10 momentarily as he receives treatment.
Valencia's cross in from the right is met by Van Persie in the box, who knocks it on for Kagawa. The Japanese player makes no mistake with the finish as United take the lead, but there's worry for the hosts as Van Persie appears to have done some damage while stretching for Valencia's ball.
Two extra minutes are added this half and Evans wins a free-kick in the Norwich half after being impeded, which he takes quickly.
Smalling lifts a cross in from the right as United try to build something in last couple of minutes but Van Persie can't get his header on target.
We're on the brink of half-time and Norwich have more than held their own in the opening half - the question is whether they can keep it up in the second. The ball rolls to De Gea in the United goal as the minutes trickle down.
Norwich are just managing to keep United on the edge of the box, closing the gaps to keep the hosts at bay, with the door eventually slamming shut as Kagawa's attempted ball through is intercepted.

Howson puts the ball behind for another United corner on the right of goal. Johnson gets to Van Persie's effort first and Holt heads it away.
A sloppy header from Turner leads to another spell of attractive United build-up until Van Persie tries his luck with an optimistic shot which he can only blast into the stands.

Van Persie does well to win a battle with several Norwich players in the Canaries' half and find space to pick out Kagawa.
Bunn is back on his feet but signals he can't take the goal-kick, with Garrido stepping in to do the honours. The keeper is continuing but for how long remains to be seen.

The teams are out at Old Trafford and it's almost time to get underway. Enjoy the first half guys and keep your feedback coming at half-time.
The sun is shining in Manchester ahead of kick-off. There's also loud, proud and yellow support from the 2,442 Canaries fans present today.
Marcus Brooks has written in - "Hoping that the team dont already have their eye on the match with madrid on tuesday. Im going for a cagey game with the little pea nicking a late winner. 2-1"
@NJLynn is going against the crowd with his prediction, tweeting - "Got a sneaky feeling Norwich might get a result today..They seem to rise to these occasions."
United have hit the woodwork 19 times this season, only Everton have done so as often, with Robin van Persie hitting it seven times, more than six Premier League sides in their entirety.
A couple of stats for you before we get underway - The Red Devils are looking to win five league games in a row for the second time this season, no other side has managed it once.
Stephen Holcroft says - "A little surprised with Fergie's selection, a strong side particularly upfront, makes interesting his starting eleven for tuesday. Come on the reds, Van Persie due a goal, 3-0 comfortably!!"
Patricio De La Rocha believes Ferguson could regret using RVP so close to the Real second leg on Tuesday - "I think Ferguson is making a huge mistake by playing vanPersie, and not using the depth of the squad. Why risk it if you have top players on the bench, why not give more minutes to Chicharito? If vanPersie get injured he will be missed against Real. You need fresh legs against Real, you have seen the quality they have got against Barcelona."
Llew Griffiths (top name) has been in touch to say - "I believe he has decided to play a good team because he knows Norwich are capable of a shock win! United 2-0 Anderson and RVP!"
Norwich, meanwhile, snatched a welcome success against Everton last weekend to end a nine-game winless run in the Premier League which has seen them slide into 12th place.
United have the opportunity to stretch their 12-point lead at the top to 15 this afternoon, with rivals Manchester City not in action until Monday against Aston Villa. Ferguson's men have won their last four on the bounce heading into today's clash.
The line circulating Twitter is that veteran defender Rio Ferdinand has flu but yet to hear United confirmation.
Rafee Ahmed has been in touch to say - "Just hope Man Utd win today to wrap up the title and show Man City how it's done who think we have been lucky...well we have done this in the last 10 to 15 years winning trophies for fun so Mancini needs to see a doctor..can't wait to see some quality goals from Rooney and RVP."
United are likely to be out for revenge after their defeat at Carrow Road in November, when Anthony Pilkington's goal on the hour mark inspired a 1-0 win.
Here's a quick line from our friends at Sky Bet: The odds are stacked against Norwich City completing a double over Manchester United. The Canaries (19/2) are one of only three teams to beat United in the league this term, but are seeking their first win at Old Trafford since 1989.
Half an hour to go until kick-off then and there's still plenty of time for you to have your say. Email email@example.com or drop me a Tweet @SkySportsRachG.
Looking at the Canaries, Alex Tettey remains an absentee with a knee injury, while Kei Kamara starts on the bench despite his super sub heroics in the win over Everton.
Rafael and Rio Ferdinand are other big names to sit out today's game, apparently rested for Tuesday's showdown at Old Trafford.
Fergie will have one eye on that blockbuster clash but he's named a strong frontline against the Canaries, with Wayne Rooney returning alongside Robin van Persie after two weeks on the sidelines.
Ryan Giggs is the notable absentee from the United squad as he is made to wait for his 1,000th career appearance - with the milestone likely to come against Real Madrid in the UEFA Champions League on Tuesday.
Man Utd XI: De Gea, Smalling, Vidic, Evans, Evra, Valencia, Carrick, Anderson, Kagawa, Rooney, Van Persie. Subs: Lindegaard, Rafael, Hernandez, Nani, Young, Welbeck, Cleverley.
